Beschreibung
Zusammenfassung:	Photo-polymerizable compositions for preparing a polymer are described, wherein the composition includes a cationically polymerizable monomer and a photo-initiating system comprising a cationic photo-initiating agent. The compositions are amenable for use in methods directed to producing polymers that cure in sites in which light penetration is not possible for inducing photo-polymerization of polymers for many applications, such as, for example, where the polymer is made in an opaque mold; where the polymerizable composition includes interfering substances such as pigments, dyes and/or fillers; where the polymer shape is thick; where the polymerizable composition needs to fill a sample having long crevices or molds with complicated shapes, angles or deep cracks and to encapsulate complex parts; or where the polymerizable composition needs to bond or adhere two substrates that may be opaque, semi-transparent, or optically thick. An apparatus and reaction vessel for forming the photo-polymerizable compositions are also described.
